SPRAYING, nnvron.

Specification of Letters Patent.

Application filed February 5, 1919. Serial No. 275,166.

To all whom it may concern: v Be it known that I, PAUL RAsoH, a citizen of Canada, residing at Chicago, county of Cook, and State of Illinois, have 1nvented new and useful Improvements in Spraying Devices, of which the. following is a specification.

The invention relates to a device for mixing and distributing chemical solutions and mixtures, and more particularly to a spraying device as employed in the administration of medicines, disinfectants, insecticides, fungicides, chemical fertilizers, and the like.

It is an object of the invention to provide a spraying device which with simplicity of construction and arrangement combines an unusual degree of efliciency.

A further ob 'ect of the invention entails the provision of a container constituting a repository for the chemical, and a tubular member for the passage of the fluid, the means for manually filling the container with chemical being also adapted to automatically discharge the chemical when subjected to the influence of the fluid.

It is a further object of the invention to provide a tubular member and a container having communication with one another, there being regulating means controlling said communication to regulate the amount of chemical to be discharged from the container.

Another object of the invention embraces the provision of means for conveniently filling the container with a chemical and for discharging the chemical in the path of the fluid egressing from thetubular member so as to assure a good mixture of solution of the fluid and chemical.

Another object of the invention constitutes the provision of means at the discharge end of the tubular member for dissipating the energy of the fluid, so that the fluid which flows from the discharge end of the tubular member will be adapted to act on the discharged chemical.

It is a further object of the invention to provide certain details of arrangement and construction of parts tending to increase the usefulness and enhance the desirability of a'deviceo'f this particular character.

To the accomplishment of the objects stated and others that will become apparent as the description proceeds, the invention comprises the means described in the following specification,particularly pointed out in" the claims forming a part thereof, and illustrated in the drawing, in which- Figure l is a sectional elcvational view of the device constructed in accordance with the invention;

Fig. 2 is a perspective view of the nozzle secured to the end of the tubular member;

Fig. 3 is a perspective view of a rotary member arranged interiorly of the nozzle and adapted to be placed in rotation under the influence of the flowing Water;

Fig. 4: is a perspective view of a ring washer carrying the rotary member;

Fig. 5 is a washer, and

Fig. 6 is a cap secured to the nozzle and holding the various parts interiorly of the nozzle in functional position.

Referring to the drawing, 1 indicates a tubular member provided at the upper end with a bead 2 and with a threaded portion 3 at the opposite extremity. A shell 4 is arranged at the upper end of the tube 1 and has an aperture equal to the outside diameter of the tubular member, so that the bead 2 forms an abutment for the casing 4t to secure the latter against removal from the tube in one direction. The casing 4 is provided with interior threads 5, into which a nipple 6 is secured, constituting a coupling for a hose 6 which may be placed in communication with any suitable fluid under pressure adapted to flow through the tube 1.

To the threaded portion 3 of the tube 1, a nozzle is secured comprising a cylindrical body portion 7 being exteriorly screw threaded at 8 and having a reduced tubular shank portion 9, equipped with interior threads 10 so as to permit detachable conperspective view of a disk nection of the nozzle with the threadedend 3 of the tubular member 1. The body portion 7 of the nozzle receives a counter bored disk 11, whose outer diameter is slightly less than the inside diameter of the nozzle casing 7, and is also formed at diametrically opposite points with two apertures 12, slantingly arranged with respect to a radial vertical plane passing through the upper edge of the aperture. The counter bored diskll is maintained on a rubber ring 13,

which in turn rests on a disk washer 14,

equipped with a restricted aperture 15, which serves for the egress of the fluid.

A cap 16 comprlses a cylindrical portion Patented July 27,1920.

A container 21, preferably, although not neces sarily, of tubular construction and having il,fis'j.secured to the tubular member by I meansfof-apluralityjof webs 22.

,uated scale 26, provided on a web 27, where- As indicated in Figlcommunication is establlshed between the upper ends of the which has a pointer 25 mounted over a gradby the available opening of the passage v is indicated The container 2lis provided with interior threads 28 at'the upper cX- tremity to receive an-end plug 29, equipped with a gland 30, and the other'extremity of the container 21 is closed up by a, plug 31, se-v cured to the threaded portion 32 at the lower extremity of the container; The plug 31 is provided with a depending angular portion 33 so as to facilitate engagement of the plug 7 with a wrench when the former is to be regmoveuor PlElCGt'llll functional position.

Reciprocatingly fitted within the con tainer 21 is-a piston 34:, whosestem 35 pro r jects through the; gland 30 and is equipped at the outer end wlth a handle POliliOil to facilitate mani nilation of the oiston. rich jacent'to the lower end of the container a pipe 37 has communication therewith.

shown the pipe is disposed to engage the 'JVELll of the tubular member 1 and tern1i-,

.nate's in a' coupling 38. which receives an- ;other pipe 39 "at its other end, and which latter pipe may be arranged either to have, its end portion near the aperture '15 of the disk washer 14. or in a position to facilitate its insertion into a receptacle'containing a chemical, and be out of interference when it is desired to disassemble the nozzle.

The operation of thedevice for the ourpose of distributing chemical, fertilizer, in-

ta-ining acertain chemical.

secticides and thelike is as follows: The

pipe 39 is turned from theposition shown in r Fig. 1 to a diametrically opposite position so as to be insertible into a reservoir con- V hereupon the handle portion'36 is sei /ed and the piston 34 raised, creating underneath the piston a vacuum whereby the chemical of the .i'eser- J Voir is sucked into the lower portion-of the container 21, After the container is filled the pipe 39 is turned intothe positionshown in Fig. 1 and the Valve 24; is set to establish communicationbetween the tubular member 1 and the container 21. If desired, the valve 2 f may be opened during the ascending stroke of the piston so as to allow for the escape of the air above the piston. When the liquid is permitted to flow through the tubular member'l it will act on the rotary disk l1 to place the same in rotation, and the ensuing retardation of the flow will be responsible for the emission of a stream of liquid which will have a comparatively low pressure. A portion of the liquid, in view -Ioftl1e communication established between the tubular containers 1 and 21,;will flow into the container 21 and will act on the piston 3 l-to graduallyfor'cethe latter into the lowermost position, thus causing the discharge of the chemical previously stored up underneath the piston within the container. l'The. amount of chcm cal chscharged from the container 21 may be regulated in accordance with the positionof the valve 24 for which purpose a scale 26 and a pointer 27 are provided.

. Vv lnle the drawing discloses the preferred embodiment of the invention, the same is susceptible of a great many modifications falling within the scope of the invention and it is, therefore, my intention not to limit myself to the structural details as shown, but to avail myself of any changes and alterations falling within the purview of the invention as set forth in the appended claims. 7
